1 Claim.

The present invention relates to new and useful improvements in loomshuttles and has for its primary object to provide, in a manner ashereinafter set forth, a device of this character comprising a spindleincluding a novel construction and arrangement for automaticallysecuring the quill firmly in position when said spindle is swungdownwardly into the shuttle but which will permit ready removal of saidquill when said spindle is swung upwardly out of said shuttle.

Other objects of the invention are to provide a shuttle of theaforementioned character which will be comparatively simple inconstruction,

strong, durable, highly efficient and reliable in use, compact, light inweight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

Figure 1 is a view partially in side elevation and partially in verticallongitudinal section of a shuttle constructed in accordance with thepresent invention, showing the spindle in raised position.

Figure 2 is a view in top plan of the invention, showing the spindle inlowered or operative position, the quill being shown in section.

Figure 3 is a view in vertical transverse section, taken substantiallyon the line 3-3 of Figure 2.

Figure 4 is a view in vertical transverse section, taken substantiallyon the line 4-4 of Figure 2.

Figure 5 is a vertical sectional view, taken substantially on the line55 of Figure 1.

Figure 6 is a view in vertical longitudinal section through one endportion of the shuttle,

taken substantially on the line 6-6 of Figure 2.

Figure 7 is a horizontal sectional view, taken substantially on the linel'! of Figure 1.

Figure 8 is a horizontal sectional view, taken substantially on the line88 of Figure 1.

Referring now to the drawings in detail, it will be seen that theembodiment of the invention which has been illustrated comprises a bodyI of the usual shape, said body being substantially hollow. Traversingone end portion of the body I is a pin 2 upon which a spindle 3 ismounted for swinging movement in a vertical plane into and out of thebody I. Extending longitudinally into the spindle 3 from its pivoted endto a point adjacent its free end is a split 4 providing bifurcations 5.The bifurcations 5 are slidable as well as rotatable on the pin 2.Further, the bifurcations 5 are resilient, the tendency thereof beingtospring together. The 5 spindle 3, of course, is to receive the usualquill 6. Also traversing the aforementioned one end portion of the bodyl, adjacent the pin 2, is a stop 1 upon which the spindle 3 rests whenin lowered or operative position, as illustrated to advan- 10 tage inFigure 6 of the drawings.

The reference numeral 8 designates a longitudinal socket in the body Iwhich communicates with the spindle receiving chamber 9 of the shuttleat the end thereof in which the pin 15 2 is located. The socket 8slidably receives a stem as which projects into the chamber 9 and whichcarries a plate ll. Projecting from the plate H is a cam l2 which isengaged between the pivoted end portions of the bifurcations 5 of thespin- 20 die 3. The cam 52 is substantially wedge-shaped as shown toadvantage in Figures 4 and 5 of the drawings. A coil spring E3 in thesocket 8 yieldingly urges the cam 12 into operative engagement with thespindle 3. The upper portions of 25 the pivoted end portions of thebifurcations 5 are recessed, as at l5, (see Figure 4) to permit thespindle 3 to contract when swung to raised position.

It is thought that the operation. of the inven- 30 tion will be readilyapparent from a consideration of the foregoing, particularly to thoseskilled in the art to which the device pertains. When the spindle 3 isswung to raised position, as seen in Figure 1 of the drawings, therecesses l5 5 receive the cam l2, thus permitting said spindle 3 tocontract and allowing the quill 6 to be easily slipped thereon orremoved therefrom. When the spindle 3, with the quill 6 mounted thereon,is swung downwardly into the shuttle to operative 40 position, the caml2 spreads the bifurcations 5 in a manner to firmly bind said quill inposition, as best seen in Figure 3 of the drawings. The yieldinglymounted plate ll rides on the pivoted end portions of the bifurcations 5and is engaged therewith in a manner to releasably secure the spindle 3in either its raised or its lowered position.

It is believed that the many advantages of a shuttle constructed inaccordance with the present invention will be readily understood, andalthough a preferred embodiment of the device is as illustrated anddescribed, it is to be understood that changes in the details ofconstruction and in the combination and arrangement of parts 55 may beresorted to which will fall within the scope of the invention asclaimed.

What is claimed is:-

A shuttle comprising a body having a chamber therein and further havinga socket therein communicating with the chamber, a pin traversing thechamber, a spindle, said spindle including resilient bifurcationsrotatably and slidably mounted on the pin, a stem extending slidablyinto the socket, a plate on one end of said stem, a substantiallywedge-shaped cam on the plate engaged between the bifurcations forspreading said bifurcations when the spindle is swung to operativeposition in the chamber, and a coil spring in the socket engaged withthe plate for yieldingly urging the cam between the bifurcations, saidplate riding on the pivoted end portions of the bifurcations and beingengaged therewith for releasably securing the spindle in operative orinoperative position.
